GPblog End of Season Awards: Underrated driver of the season

As is tradditional at GPblog, we end the Formula 1 season with an awards ceremony. One of the awards is for the underrated driver of the season. Max Verstappen recieved plenty of plaudits (and rightly so) but who else performed really well? This award goes to one of the Dutchman's former teammates who has perhaps gone a little bit under the radar.
